A note of discovery on Do Not Print

FYI to someone who may be having problems with Do Not Print Elements:

It seems that the elements (in my case, class names) must be listed in the order in which they are encountered in the code. This appears to be true whether the list is in the shortcode itself or the Print-o-Matic settings.

Another pointer: I thought I had all the necessary Do Not Print elements accounted for while testing in WP post-preview mode. However, once the post was actually published, I had to add more elements to Do Not Print.

Neither of these points are criticisms of PoM, with which I’m becoming increasingly impressed. These are just “discovered rules of the game” that I hope are of help to someone else.
